EC2 Burst Calculator

Compare AWS burstable instances (t3a, t4g, t8i) with the cheapest non-burstable instance that has the same physical processor and vCPU count — exact memory twin when it exists, otherwise the closest size.

Comparison

Model: 1 CPU credit = 1 vCPU at 100% for 1 minute; the daily peak block is served at the end of the active day from an initially empty credit bucket. Surcharges and credit tables come from the generated dataset (see ec2-burst-spec.json for sources). REST APIs and other non-CPU fees are not included.
